Abstract

EL DISPOSITIVO DE OBTURACION DE UN TUBO (1) DE AMORTIGUADOR HIDRAULICO PRESURIZADO EN EL QUE SE DESLIZA UN PISTON (7) PROVISTO DE UN VASTAGO AXIAL (8), COMPRENDE UN TAPON (17), UNA JUNTA DE ESTANQUEIDAD (10), MEDIOS DE FIJACION (19 A 22) Y UNA GUIA (18) CILINDRICA CUYA ABERTURA CENTRAL (18C) GUIA EL MOVIMIENTO AXIAL DEL VASTAGO (8). LA GUIA PRESENTA UNA BASE DE GUIA (18A) Y UNA PARED PERIFERICA AXIAL (18B) QUE DEFINE UNA CAVIDAD CIRCULAR PARA SOPORTAR Y CENTRAR LA JUNTA DE ESTANQUEIDAD Y EL TAPON. LA BASE PRESENTA VARIAS PERFORACIONES (24) REPARTIDAS POR UN TRAYECTO CIRCULAR EN EL FONDO DE UNA GARGANTA ANULAR (23) PRACTICADA EN SU LADO SUPERIOR. EL TAPON (17) PRESENTA UNA ABERTURA CENTRAL (17A) CUYO DIAMETRO ES SUPERIOR AL DIAMETRO DEL VASTAGO DEL TUBO PARA DEFINIR UN JUEGO RADIAL QUE EVITA EL CONTACTO MECANICO ENTRE EL TAPON Y EL VASTAGO DURANTE EL FUNCIONAMIENTO DEL AMORTIGUADOR. EL TAPON PRESENTA UNA CAVIDAD CIRCULAR (17B) ALREDEDOR DE SU ABERTURA CENTRAL PARA RECIBIR UNA PARTE DE LA JUNTA DE ESTANQUEIDAD SITUADA ENTRE EL TAPON Y LA BASE DE GUIA.THE OBTAINING DEVICE OF A PRESSURIZED HYDRAULIC DAMPER TUBE (1) IN WHICH A PISTON SLIDES (7) PROVIDED WITH AN AXIAL VASTAGO (8), INCLUDES A PLUG (17), A SEALING SEAL (10), MEANS OF FIXATION (19 TO 22) AND A GUIDE (18) CYLINDER WHOSE CENTRAL OPENING (18C) GUIDE THE VASTAGO AXIAL MOVEMENT (8). THE GUIDE PRESENTS A GUIDE BASE (18A) AND AN AXIAL PERIPHERAL WALL (18B) THAT DEFINES A CIRCULAR CAVITY TO SUPPORT AND CENTER THE SEALING SEAL AND THE PLUG. THE BASE PRESENTS VARIOUS PERFORATIONS (24) DISTRIBUTED BY A CIRCULAR JOINT ON THE BACKGROUND OF AN ANNULAR THROAT (23) PRACTICED ON ITS TOP SIDE. THE PLUG (17) PRESENTS A CENTRAL OPENING (17A) WHOSE DIAMETER IS HIGHER THAN THE DIAMETER OF THE TUBE VASTAGO TO DEFINE A RADIAL GAME THAT AVOID THE MECHANICAL CONTACT BETWEEN THE PLUG AND THE VASTAGO DURING THE OPERATION OF THE SHOCK ABSORBER. THE PLUG PRESENTS A CIRCULAR CAVITY (17B) AROUND ITS CENTRAL OPENING TO RECEIVE A PART OF THE SEALING BOARD SITUATED BETWEEN THE PLUG AND THE GUIDE BASE.
